Steve: Please recycle, bye, see ya!
Michael T. Smith is credited as Michael Smith.
The closing credits included: "Thanks to our interns: Patrick O'Donnel Matthew Reinhart Lisa Schanen"
Alice Wilder is credited as Dr. Alice Wilder and in addition to directing the episode, she is one of Steve's Friends (additional voices) in this episode. David Burger is credited as "Duke" David Burger.
During the "So Long Song," Steve adds in "please recycle" even though the episode itself has nothing to do with recycling.
The title of the episode might be a reference to the so-called "lost" episodes (pilots, unaired scripts, etc.) that are common in many shows.
Mailtime Segment: Mailbox lost Steve's letter. So he goes back outside, retracing his path and finds it. In the letter, a girl lost her red sweatshirt while playing at the park, so she and a group of her friends look around in the different areas they played for it. They eventually find it sitting on a swing.
